Problems solved by technology

[0002] The ordinary fingerprint module does not have the function of time stamp and digital signature, nor does it have the function of storing and verifying fingerprints. It only needs to collect fingerprints and data interfaces, and it needs to add a complex algorithm processing system to provide complete fingerprint services. The intermediate links can easily cause users to privacy leak

Embodiment Construction

[0014] The specific embodiment of the ultra-strong security fingerprint module of the present invention is that the main controller adopts a programmable microcontroller with an acceleration sensor, a built-in memory unit, an external SE module with NFC function, and a fingerprint sensor. The user uses it for the first time. It needs to be controlled by the application program of the external device, and the user's fingerprint data is obtained through the main controller for analysis and processing to form a fingerprint template, write it into the built-in memory unit, and set the encryption authentication method, and then it can be used normally.

[0015] When the user's fingerprint does not match, the main controller does not send a wake-up signal. When the fingerprint matches and a wake-up signal is generated, the back-end device obtains the verification result and time information with a digital signature through the data interface to determine whether to continue the follow...

Abstract

The invention discloses a super-safe fingerprint module, which is internally provided with a sensor interface, a main controller, an algorithm processing module, a timer unit, a safe memory and a datainterface, wherein the main controller reads fingerprint data through the sensor interface, gives out a fingerprint acquisition instruction with current reference time and a digital signature for work according to an external trusted execution program, and the main controller verifies the passing of the digital signature, encrypts a collected fingerprint data or fingerprint comparison result, performs digital signing on encryption result and timing cut-off off and then outputs the digitally signed encryption result and timing cut-off time through the data interface; and the safe memory can store a public key for verifying the digital signature of the instruction, a data encryption key and a signature key, can also store a plurality of fingerprint templates and a gesture control template and supports multiple applications such as mobile payment, public transportation and access control.

Description

technical field [0001] The invention relates to a pre-comparison algorithm, a security fingerprint module with a digital signature and a time stamp, which can be used in high security mobile phones or security equipment. technical background [0002] The ordinary fingerprint module does not have the function of time stamp and digital signature, nor does it have the function of storing and verifying fingerprints. It only needs to collect fingerprints and data interfaces, and it needs to add a complex algorithm processing system to provide complete fingerprint services. The intermediate links can easily cause users to Privacy leak. If these functions are integrated together, it can greatly simplify the design complexity of safety equipment and reduce the cost. Contents of the invention [0003] The invention discloses a super strong security fingerprint module, which is characterized in that it has a built-in sensor interface, a main controller, an algorithm processing modu...
